The pilot and co-pilot escaped ejected from the plane
Investigators have concluded that engine failure was the cause of the accident near the Torness plant in East Lothian in November 1999.
In an accident summary, the Ministry of Defence commended the two crew members for demonstrating "exceptional levels of airmanship and awareness in the most adverse of conditions".
The pilots, based at RAF Coningsby in Lincolnshire, were injured after they ejected from the £20m aircraft, which was destroyed by the impact with the water.
One of the airmen suffered spinal injuries and his colleague sustained facial injuries.
The report said they had ensured that the Tornado was clear of the power station before abandoning the aircraft.
After landing the two men used a mobile phone to call for help and then walked to a farmhouse, where they were given tea and biscuits.
They were picked up 15 minutes later in the village of Birnie Knowes and taken to the Edinburgh Royal Infirmary for treatment.
Salvage operation
The F3 Tornado had been taking part in a low-level, night-time navigation exercise, flying from the air force base at RAF Coningsby in Lincolnshire.
It caught fire about seven miles south of the power station.
The aircraft's accident data recorder was recovered, during a lengthy salvage operation, along with 80% of the wreckage.
An examination of this data suggested that a parts failure had led to the blaze.
As a result, engine modifications have been recommended by investigators.
